A 0.100 m solution of which one of the following solutes will have the highest vapor pressure? A)KClO₄ B)Ca(ClO₄)₂ C)Al(ClO₄)₃ D)sucrose E)NaCl

Question

Quizplus · Accepted Answer

The solute with the highest vapor pressure will be the one with the lowest boiling point, as it will have a higher tendency to evaporate. Out of the given options, only sucrose is a molecular compound that does not dissociate in solution, and therefore it will have the lowest boiling point and the highest vapor pressure. The other options are all salts and will dissociate into ions, which will lower the vapor pressure.
